[arm-allstar] Fan control via GPIO and control circuit you can get from Amazon

[Arthur Putnam]

I would like to turn it on via PTT of pi for a time period. Then shut down. Not sure if CPU temp could also be monitored and activate as same as PTT .  Once a temp range was reached?
Too many bun fans running all the time here in the shack.

 Yes, that module will control a 120V fan from an I/O bit on the Pi fine.
But decide what you want to do regarding controlling it. Leave it on, in
which case you don't need the module, turn it on on TX, turn it on on TX
with delay, Control it with a temperature sensor?
